Abstract

PURPOSE:To secure such a plastic leisure boat that will not founder even in case of breakdown or being holes in the bottom, by constituting the hull with a double wall construction so as to make up a hollow part with a plastic material being excellent in rigidity. CONSTITUTION:A boat body 1 is formed into a hollow body in a double-wall construction consisting of an outer wall (a) and an inner wall (b). This double- structure hollow body forms the stem 2, the stern 3, the bottom 4 and the boat's sides 5 and 5 as a separated hollow part each. Even if the outer wall (a) of the hull 2 gets holed due to a collision or the like, the boat is confined only to submersion inside the hollow body of this double-wall construction, thus it can escape from foundering.

Description

[Detailed description of the invention] This invention is recessed into a leisure port made of synthetic resin.

A convenient leisure port is a rubber or wooden rubber boat. However, if the flexible rubber float bladder that holds the hull of a rubber boat is damaged, the air will escape and the boat will not only lose its buoyancy.

The hull is deformed and it becomes impossible to board the ship. Additionally, if a hole is made in the hull of a wooden boat, water can flood through the hole and cause the boat to sink.

The purpose of this invention is to eliminate these drawbacks, and by making the hull a double-walled structure with a hollow part consisting of an inner wall and an outer wall, made of a rigid synthetic resin material, there will be no holes in the outer wall. The purpose of the present invention is to provide an extremely safe leisure port made of synthetic resin without the risk of the ship's hull sinking or deforming.

In addition, according to this invention, the double wall 4.4η structure with a hollow part is made of a synthetic resin material with a light specific gravity.
A leisure boat made of synthetic resin that will not sink even if the hull capsizes or the cabin becomes full of water due to waves, etc.
・It provides:

That is, the present invention provides a structure in which the hull is made of synthetic wood 1111 having rigidity.
The main feature is a leisure hoard made of synthetic resin, characterized by having a double wall structure so as to form a hollow part.

To explain this invention with reference to the illustrated embodiment, the hull (1) is formed into a hollow body with a double wall structure consisting of an outer wall ((2) and an inner wall (1)). This double-walled hollow body may be one whole or a number of interconnected hollow bodies9, for example, the bow (2), stern (3), and bottom (4).
), and further may be formed as an independent hollow body having left and right sides (5) (51).

Therefore, in the boat according to the present invention, even if a hole is made in the outer wall (a) of the hull (1) due to a collision or the like, water will not enter the hollow body of the double wall structure consisting of the outer wall (α) and the inner wall (bl). The hull (1) remains in place without any risk of deformation.
It can be used as is by simply deepening the draft slightly.

In addition, even if the hull (1) capsizes or the interior of the hull (1) becomes full of water due to waves, etc., the hull (1) will be protected from the outer wall (α) and inner wall (bl) by the synthetic resin material with low specific gravity. Because it is constructed as a hollow body with double wall structure.

Its buoyancy prevents it from sinking. In particular, as in the illustrated embodiment, if the bow (2), stern (3), or bottom (4) are each formed into independent hollow bodies, the hull (1)
Even if the vessel capsizes, if one of the hollow bodies is intact, the vessel (1) will not sink and the vessel (1) itself can be used as a life preserver, making it extremely safe in the event of an emergency. . However, the main application is for synthetic resin.

It is also easy to form the whole in one piece and can be produced at low cost.

In this way, according to the present invention, the hull has a double-walled structure with a hollow portion consisting of an inner wall and an outer wall.
Even if the outer wall is damaged, the hull will not be deformed and can be used as is by simply lowering the draft slightly.

Further, according to the present invention, since the hull has a double wall structure having a hollow portion consisting of an inner wall and an outer wall, 61
Even if the hollow body capsizes or becomes full of water due to waves, etc., there is no risk of sinking due to the buoyancy of the hollow body.

Furthermore, this invention has the practical benefit of being able to be produced at extremely low cost by integrally molding 9 synthetic resins.
